Locator/ID Separation Protocol (LISP) Impact
Abstract
The Locator/ID Separation Protocol (LISP) aims to improve the
Internet routing scalability properties by leveraging three
principles: address role separation, encapsulation, and mapping. In
this document, based on implementation work, deployment experiences,
and theoretical studies, we discuss the impact that the deployment of
LISP can have on both the routing infrastructure and the end user.

RFC 7834 LISP Impact April 2016
1. Introduction
The Locator/ID Separation Protocol (LISP) relies on three principles
to improve the scalability properties of Internet routing: address
role separation, encapsulation, and mapping. When invented, LISP was
targeted at solving the Internet routing scaling problem [RFC4984].
There have now been years of implementations and experiments
examining the impact and open questions of using LISP to improve
inter-domain routing scalability. Experience has shown that because
LISP utilizes mapping and encapsulation technologies, it can be
deployed and used for purposes that go beyond routing scalability.
For example, LISP provides a mean for a LISP site to precisely
control its inter-domain outgoing and incoming traffic, with the
possibility to apply different policies to different domains
exchanging traffic with it. LISP can also be used to ease the
transition from IPv4 to IPv6 as it allows the transport of IPv4 over
IPv6 or IPv6 over IPv4. Furthermore, LISP also supports inter-domain
